[Mate 8 General] jbmc83:
i leave it on smart mode but turn on airplane mode, that way im only using anywhere between 0-3% overnight :) so with ultra mode it should be in the range of 0-1%
[Mate 8 General] ajsmsg78:
It seems that enabling double tap to wake drains significantly more battery. My Android System usage after enabling it was at 25% today and I only have 4 hours of screen on time and my battery is down to 22%. I was also getting random black screens when trying to unlock until I disabled it. This is why Huawei didn't enable it on the Mate 8. The same issue happened with my Mediapad X2 and it took about 5 updates to get it working properly. I'm sure in the future it will be enabled and working well.
[Mate 8 General] themissionimpossible:
On my ex Huawei Honor 6 Plus 5.5" w/ Lollipop the DTW doesn't use any significant battery power, and that phone has a Kirin 925 processor, so there is no apparent reasons why on Mate 8 it should use more power.

I too hope that the currently observed battery drain was caused by a not yet complete and correct implementation of this functionality...
[Mate 8 General] drexappeal:
I might try Smart mode tonight. Ultra battery mode, while the device barely drains between 0-1% for me, it does seem to undo some of the defaults I have set, like taking Messenger off as my default text messaging app.
[Mate 8 General] hamer_83:
Please help me!

My battery is drain and I don't know how to fix it.

The problem is caused by Android System and SO Android.

Yesterday I had wipe data, wipe partition, clean all Android Services cache but thw proble continues.

Please help [emoji17]

[Mate 8 General] drexappeal:
In reading the first part of your statement, I thought there was a double tap to wake funciton that I didn't see anywhere and might have overlooked. But after reading thoroughly through, I actually love the fingerprint sensor on the Mate 8, which wakes the phone. What I did/do, and it's similar to what I've done in my devices for the past 4 years, is use Widgetlocker in addition to the fingerprint sensor. That way, when I wake the phone with my fingerprint, there's still a lockscreen that prevents unnecessary touches, prior for me needing to do whatever I have to do on my phone. Only quirk of using Widgetlocker on the Mate 8 is that I can seem to figure out how to fix the settings, so it will allow me to edit my lockscreen. My workaround has been to create/edit the lockscreen on one of my phones, and then use Pushbullet to send over the backup.

Anyhow, just wanted to share my 2 cents, although it would be really nice to have the double tap to wake. I do have double tap for "screen lock", courtesy of Nova Launcher. I linked the double-tap function (gesture in Nova Launcher settings) to the "screen off" app. I'm not sure if that is a stock Huawei app or if it's a stock Marshmallow function, but it was pre-loaded on my Mate 8 and it works perfectly! Only down side is that it only works on the homescreens (which, I think is the same way it works on LG phones), but it is awesome to not have to hit the power button to put the phone in standby.

Battry

My phone's battery consumption on Android system. Consumption is always at the top. Night from 12 pm to 6 am about 6 percent of consumption. Mate 7 nights before I was 1%. I feel like Mate 7 is not strong consumption and high phone battery, update firmware, I still was not 185 b103. Excuse my English is not good.:(

ایرانی های عزیز اگه هستند کمک کنن
[Mate 8 General] icy20:
At my phone the bigger consumption is from android system on which the app with the most milliamps is the settings... LOL wtf? Second consumption is on hardware phone calls and then SOT... How is that even possible?
[Mate 8 General] jbmc83:
ok the race is on, heres what im gonna do next: leave the display on, minimal brightness, airplane mode on and all sensors switched off, no apps running in the background... lets see whos got the best SOT value then, ha![emoji14]

Hey

Then if I root my stock rom every thing would be ok?

All the apps work?

Does huawei apps and system apps work properly?
[Mate 8 General] ajsmsg78:
Yes. You just have to have twrp then backup your current rom then flash KangVIP, it's prerooted so you won't have to root.
[Mate 8 General] farzamirani:
Thank you

Wheter or not I can root the huawei stock roms with this method to? And rooting with supersu?

Another question is is there any way to rootback? (Unroot) is it simple?

And another thing that after flashing twrp and flashing the rom....

Im supposed to flash twrp with adb again whenever I need it or not just with pressing buttons it boots?
[Mate 8 General] ajsmsg78:
You only need to flash twrp once and it will stay. If you want to root the stock rom you just have to flash SuperSU 2.71. It's a systemless root. If you want to go back to stock then simply restore the stock rom you backed up before you rooted in TWRP.

[Mate 8 General] tucker2:
Hi again,

When i got the phone it was on C636B103 (i had the exact draining problems on B103) then i update it to B180 with dload method and made a factory reset, wiped cache with stock recovery and Android System drainage was like %20-%40 for the first day with B180.And day by day it started increasing and i really dont know WHY or HOW.

Usually i'm a normal user, don't push hard hardware, don't play games for hours, don't surf on net or chat for hours etc. just using normal.With this usage i got max 4.32h SOT in 49 hours.

Every single night i got around %10-%15 battery drain in 9 hours with No Wifi, No Mobile Data, just Sycn is ON.

Also yesterday night i started to use GSam Battery Monitor and System Monitor Apps.As Gsam shows i have 12h SOT (Since Last Full Charge – Unpluged at %100 battery at 12.04.2016 on 01.00 AM).How this can be possible ? lol.When i choose Since Last Unplugged it shows 1,23h SOT.

Guys i’m really really confused about that battery problem.I don’t know what is the solution or there is a solution with stock roms but i don’t want to ROOT and flash a rom yet, maybe in future but not yet.Please someone help me about this.

Here are the Options i setted and screenshots;

•	Using with - Smart Power Plan

•	Keep Wifi on when sleeping - Always (I tried Never option, its doesn't matter) + I'm using wifi max 1 hour in a day

•	Mobile data always on - ON

•	Stock Mail App and Gmail using with PUSH option

•	Brightness – AUTO

•	Sycn – On 7/24

Edit: GPS is always OFF and google apps dont use it and i don't use SD Card
[Mate 8 General] themissionimpossible:
Try manually terminating both these apps during nights,a PUSH protocol active without an available connection might be the cause of the high overnite battery drain.
[Mate 8 General] tucker2:
I will try, thank you.
[Mate 8 General] jbmc83:
also, just check the screen on time via the inbuilt battery manager. there are a lot of battery monitoring apps out there that reset once u reboot the phone or connect it to a power source (be it power socket or computer, even for a short while), thus giving u false sot values.

btw, still on L29 B162 firmware and settling in at 8-10 h SOT depending on usage. totally happy with that :)

Yesterday i completely remove stock mail app account and get Outlook from play store - Sync, mobile data, wifi and auto brigthness are OFF.So i had %7 drain last night in 10 hours.

[MENTION=4294020]jbmc83[/MENTION]

You may be right, at that moment i have 2.40h (inbuilt battery manager) SOT and got %38 battery.Also Android System Usage is %67.44 right now.

Does your phone on L29C636B162 or other build number ?

If it is posibble, could i jump to B162 with dload method again ? (im on B180 now)

[MENTION=1071539]dlorean[/MENTION]

Good for you mate ! I'm really proud of your phones.lol

How can i disable Doze ? I couldnt see anything about it :/

It's okay mate, thanks for your effort.I knew it will be like that :/ I'm thinking of changing of my carrier, it may help ? Also i will create a new Google Account and i will try with it after a factory reset ?

Do you have the exact information about; now im on B180 (i loaded it on to B103 with dload) and im thinking about to go back 103 with dload method, is this posibble ? or If is there any more roms for C636 i can try them too ?
[Mate 8 General] themissionimpossible:
From your screenshots it looks like your Mate 8 is/was under 3G network, correct?

Possibly there might be a difference if under 4G coverage (actually tucker2 didn't said which network he's using).

BTW, your Android System battery drain has been about 46%...
[Mate 8 General] tucker2:
Yes, you are right.It's on 3G all day, i never switch off in a normal day usage of phone.Only at nights i switch off it.

You mean if i switch to 4G, i will have less drain ?

---------- Post added at 02:14 PM ---------- Previous post was at 02:06 PM ----------

Opss sorry i think you mentioned me ^^ lol
[Mate 8 General] jbmc83:
naturally, since i havent used the phone at all during those 7 hours :) so what else is there to drain battery aside from the system? ^^ 46% of 2% is a total of 0.9% battery drain by android system over the course of 7 hours, i think i can live with that ;)

[Mate 8 General] dj69holland:
With B172: i did some battery tests with different scenarios.

each scenario, i did over a night and day, with GPS off, Sync off, etc and with both dual sim radio active, as well as android doze disabled.

- On Wifi only [over one night ~8hrs, battery drain approx 8-12%]

- On 4G only [over one night ~8hrs, battery drain approx 1-3%]

- On 3G only [over one night ~8hrs, battery drain approx 1-2%]

So seems like something to do with wifi is causing some drain, are others having similar symptoms. or does someone know what it could be.

my next phase of testing will be to find out what is causing it.
[Mate 8 General] farzamirani:
​

Yeah if you read last posts you'll see our posts... I have found this before.... the reason is that when you put the phone on mobile data after sleeping it turns off the mobile data automatically it means actually you dont have any network connection....although it turns it on periodically for syncing and getting things up to date....but when you put the phone on wifi ( keep wifi on during sleep) the system doesn't turn it off whole night.... so you will have 1% battery drop every hour....

But I couldnt find why this drainage exist its so irritating I even have turned off the automatic sync....

I have tried any thing flashing, reseting ,wiping the cache changing the rom, nothing works.... hopefully we should wait for an officiall update that fix this problem...jut know that you are not alone....

The problem is some thing about android system that eats the battery and keeps using the cpu even in sleeping as the battery manger says however when I cheked with cpu monitor it is in deep sleep whole night but the android system counts m.A. actually it is a paradox .... im really overwhelmed....
[Mate 8 General] dj69holland:
Yes i did read all the posts before, and aware of it. I was just sharing what i had tested.

I do agree that it is an irritating drain, And do plan to isolate what is causing the issue while on wifi, and in each phase of mine dig a bit deeper.
[Mate 8 General] bluheart:
If you keep whatsapp or messenger on whole night, they will.continuously check for messages and will actively sync. This active syncing happens more.often during WiFi because of the settings made in.WiFi.

I get 2-3% drain overnight with WiFi and 3G on but no.apps in.memory

;)
[Mate 8 General] ajsmsg78:
Android system may be at the top for some and you would think it's draining the battery but it's not. I flashed my new build of Simply Google B172 the other night and took the phone off the charger. I had work, then my bowling league so I left the phone unplugged on my desk on 4G (only 1-2 bars of 4g) for 11 hours and my battery was at 98% when I got home. That's a 2 percent drain every 11 hours. Android System was at the top of the list with 44.75% because the phone wasn't being used. This is not a battery drain in my case, and i'm getting extremely great battery life.
[Mate 8 General] farzamirani:
Yeah I guess it myself but why other phones dont have this drainage over night with wifi on and whatsapp?

So you say what should I do with whatsapp overnight?

Should I force stop it?

---------- Post added at 09:45 PM ---------- Previous post was at 09:42 PM ----------

Hey I kno what you say but our problem is diffrent we are drainage about 15% for 11hours!! Without even touching battery....and the only consumer is android system!

---------- Post added at 09:46 PM ---------- Previous post was at 09:45 PM ----------

And if it is about whatsapp why the whatsapp section doesn't show the usage and it is counted in android system!
